MECHANISM FOR BURNING HYDROCARBONS.

SPECIFICATION formingpart of Letters Patent No. 607,694, dated July 19, 1898. Application filed December 28, l89 7 Serial No. 663,852. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM L. Muns- FELDER, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio,-have invented certain new and useful Improvements in Mechanism for Burning Hydrocarbons, of which thefollowing is a specification.

It is my purpose to burn usually keroseneoil as the preferred hydrocarbon.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the accompanying drawings, making a part of this specification, Figure 1 represents a front elevation of mechanism embodying my invention. Fig. 2 represents atop View of the same when the cover has been removed. Fig. 3represents avertical transverse section of the same, taken in the plane of the dotted lines 3 3 of Fig. 2. Fig. Arepresents another vertical transverse seotion-to wit, one taken in the plane of the dotted lines 4 4 of Fig. 2; Fig. 5 represents a top view of a modification of the mechanism. In this View a portion of the top is broken away to disclose the interior construction.

I will now proceed to particularly describe my invention.

A indicates a casing or shell of suitable material to withstand heat. This casing is hollow and is open at the bottom and the top. Preferably the entire bottom is open. Not far below the top, along an inner side of the casing and occupying a portion of the opening in the top of the casing, there is located a gutter B, closed at each end. In this gutter I place a material 0, adapted to take up the hydrocarbon and adapted after the hydrocarbon is lighted to give it forth to the flame. Thus layers of wire may be used; but I prefer to use asbestos, and I closely pack the gutter with this substance. There remains an elongated opening (passage-way) D, preferably as long as'the inner space of the casing A and of considerable width.

Outside of the casing A and just above the extended plane of the'upper edge of the gutter I locate a pipe E. This pipe extends horizontally along near the casing and is duly connected with the reservoir or source whence v the immediate supply of hydrocarbon is ob tained. At the terminal end of this pipe I locate a burner F, and the latter is quite near or at one end of the casin g. A second burner G is located on the pipe E and near the midlength of the casing, but to that side of the mid-length in which the burner F is not pres ent. Both burners preferably extenda short distance over the gutter B and its asbestos filling, as shown.

The hydrocarbon-pipe F after leaving the casing may extend in any desired direction. The dotted lines F show how it may be extended in a straightline but I prefer to curve it back and extend it above and parallel to that portiee. of the conduit E first described, thus forming a portion E substantially as shown in Figs. 1 and 3.

Convenient means of supporting the co11- duit E are to be employed. The preferred means for this purpose consist as follows: A short flange A rises from that edge of the casing which is nearest conduit E, and the burner passes through a close-fitting opening in this flange. A bracket-clamp II is present, whose leg II is secured to the outer side of the casing A, preferably by a boltand nut H The arm or finger II of the bracket comes up against the lower side of the conduit E and passes up and partially around the rear side of the conduit, substantially-as shown. Thus the conduit E and its burners are firmly supported in place.

To better promote the desired draft and combustion, the walls of the casing incline downward and apart as they go downward, substantially as shown. A removable cover K sits upon the top of the casing and is provided with suitable means for lifting it from the casing and replacing it. The preferred means is a handle K part of which is shown in Fig. 3. The under side of the front and two end edges of the cover each have a downwardly-dependin g edge flange Kiwhich when the cover is set down in place fit down over the respective adjacent upper edges of the casing A. To prevent the cover from slipping forward, it is provided at its rear corners with downwardly-depending lugs K Kiwhich latter respectively fit into recesses A in the corresponding corners of the upper part of the casing.

The manner in which my invention operates is as follows: The hydrocarbon is allowed to flow .through the conduit TEE and runs out at the burners F and G into the asbestos packing O. The operator immediately lights the hydrocarbon in the asbestos and lets the machine take care of itself. The heat generated by the burning hydrocarbon on and in the asbestos rapidly heats the conduit and burners, as well as the casing and the asbestos, and the former thereupon generate hydrocarbon vapor and expel the same with force through the burners and over the asbestos and across the casing and over and across the upper portion of the passage-way D of the casing. At the same time air within the hot casing being heated by the latter rises through the passage-way D. As it (this hot air) passes above the opening the hydrocarbon vapor is forcibly blown or injected into it and a most thorough mixing of the vapor and the air is at once effected. Nor is this all. The combined and mixed air and vapor deflected from and by the front side and the top of the casing and seeking the highest outlet of escape pass out through the opening D of the casing. The greater portion of the burning intermixed air and vapor passes below the conduit E and then rises, while a smaller portion of this mingled air and vapor passes out above the conduit E, and farther out beyond the conduit meet and combine with the burning air and vapor rising from below the conduit. The burning of these gases results in a broad and intensely-hot sheet of flame, which not only continually heats all of the casing and the conduit E and E but also has a-large quantity of caloric to spare to be utilized as desired.

One great advantage of my devices results from the forcible injection of the hydrocarbon vapor, thus the more thoroughly intermingling the air and vapor.

Other burners, so far as I am aware, mixthe vapor with the air by allowing the air to come up around the vapor and,as it were, submerge it. Such a process is obviously not as eifective within a compact machine and a small compass as is my mechanism.

When desired, the shape of the casing in plan view may be changed. In such event the conduit will be bent to accommodate such change. Thus in Fig. 5 I have illustrated one desirable form of modification. Here the casing and its accompanying conduit (viewed from above) assume the shape of a half-circle.

Particularly attention is drawn to the following important facts: The air risingin the chamber strikes the roof and is deflected in a horizontal direction toward the passageway D. The hydrocarbon is thrown out horizontally from the jets, and in the form of jets directly into the outcoming air. The air and vapor thus meet while going in opposite directions. The air is thus interpenetrated with the hydrocarbon. These combinedviz., in a close and thorough intermixtu reare forced out together at the edge of the burner and against the generatingpipe and burn in front of the latter and above, below, and behind the latter.
